2 Claims. 1

This invention relates tobuilders? hardware of the character commonly called door stops and the primary aim is to provide unique, novel and effective means attachable to the side of a swin ing door for selectively arresting its movement at any point throughout its path of travel.

One of the primary objects of this invention is to provide a door check capable of holding the door against. movement. in either direction about itssupporting hinges through the application of an. upward force created by a specially designed foot shiftable to and from a place be.- neath the lower edge of the door when the. check is. shifted. toan operative condition.

Another object of my invention is to provide a door check having the aforementioned characteristics and that is provided with a body formed of a single piece of strap material having inherent resiliency sufficient to exert a holding force on the door when a part of the body is in operative position.

Other objects of the invention include the particular manner of supporting the door engaging body by a bracket attachable to one side of the door and through the medium whereof the body is maintained in an inoperative position for quick and ready release.

Additional aims will appear during the course of the following specification referring to the accompanying drawing, wherein:

Fig. 1 is an edge elevational view of the door check made in accordance with the present invention and showing the same mounted upon a swinging door and in a place to retain the said door against accidental movement.

Fig. 2 is a similar view illustrating the movable body of the door check in an inoperative position.

Fig. 3 is a front elevational view of the door check mounted on a door, and

Fig. 4 is a fragmentary sectional view taken on lineIV-IV of Fig. 3.

In the form of the invention chosen for illustration, the check is bodily mounted upon a swinging door l0 mounted on conventional hinges (not here shown) and movable to and from a closed condition. The door check comprises a bracket broadly designated by the numeral l2 and a body l4 formed of flat material to present a contour and shape, as clearly shown wardly inclined from its highest end to a point of juncture it with the outer end of leg 22. The inner end of leg 18 is upturned to present a stop 28 against which the door will bear if inward force on the body adjacent to foot I 5 is sufiiciently great to compress leg [8 and move stop 28. against the side of door lfll. It is the upward force of leg; l8 against, the lower edge 2!! ct door if! that holds the door against accidentalswinging in either direction. When foot is is withdrawn from beneath door it, leg i8 moves back to its normal position, as shown in Fig. 2, where the distance between leg 22 and the free end of leg I 8 is substantially greater than the distance between the bottom of door I!) and the underlying surface 24 of the floor.

Foot l t is formed at one end of body It and an eye 30 is created at the other end thereof. This eye is elongated as clearly illustrated in Figs. 1,

2 and 4, and it is through the medium thereof that body it is swingably mounted upon door as through the medium of bracket l2. A cross pin 32 forming a part of bracket 12 is threaded through eye 30 when the door check is assembled and this pin 32 is free to move along the length of eye 30 when body I4 is shifted from that place shown in Fig. l to the position shown in Fig. 2. Pin 32 is carried directly by spaced apart cars 34 of bracket l2 and the base-p1ate of this bracket 12 is provided with perforations through which screws 36 are driven when the check is mounted. When body !4 is in the position illustrated in Fig. 2, pin 32 is at one end of eye 30 and the flat wall of body M is adjacent to the flat surface of bracket l2 lying between ears 34. Thus aocidental outward movement of body M around the axis of pin 32, is precluded because body it cannot s0 swing until it is first lifted to bring pin 32 to the opposite end of eye 39 from that occupied when the parts are as shown in Fig. 2. The width of body l4 should be substantially as shown in Fig. 3 for an appreciable amount of surface 24 should be engaged by leg 22 as leg it is forced against door l0.

Bracket l2 may be cast or otherwise formed and eye 3%! should be of such length as to allow freedom of movement of pin 32 therealong when the body it is shifted from the condition shown in Fig. 1 to that illustrated in Fig. 2. Body Hi is unitary in structure, may be formed of a single a3 strip of initially flat metal or the like and, therefore, is cheap to manufacture and requires no assembly operations.

Such modifications as fall within the spirit of the invention and scope of the appended claims may be enjoyed without departing from the purview of the concepts.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:

1. For a door having a vertical side wall and a bottom edge spaced above a planar surface, a check comprising a bracket provided with a hinge pin and adapted for mounting on said wall of the door; and a body having an elongated arm provided with an eye at one end thereof for pivotally receivin said hinge pin, and a wedge shaped foot formed from resilient material and project ing laterally from the opposite end of the arm, said foot including a leg perpendicular to the arm and a member extending from one end of the leg remote from said arm into overlapping relationship to the leg, said foot being movable to and from a position wedged between said edge of the door and said surface as the arm is swung on said hinge pin, said arm being in spaced, substantial parallelism with said side wall of the door when the tongue is in said position.

2. For a door having a vertical side wall and a bottom edge spaced above a planar surface, a check comprisin a bracket provided with a hinge pin and adapted for mounting on said wall of the door; and a body having an elongated arm provided with an eye at one end thereof for pivotally receiving said hinge pin, and a wedge shaped foot formed from resilient material and projecting laterally from the opposite end of the arm, said foot including a leg perpendicular to the arm and a member extending from one end of the leg remote from said arm into overlapping relationship to the leg, said foot being movable to and from a position wedged between said edge of the door and said surface as the arm is swung on said hinge pin, said arm being in spaced, substantial parallelism with said side Wall of the door when the tongue is in said position, said eye comprising an elongated loop having its major axis parallel to said arm and formed by rebending said one end of the arm upon itself, one end of the eye bearing against the hinge pin when the foot is in said position, the opposite end of the eye resting on the hinge pin when the foot is swung to an inverted position above the bracket, said eye cooperating with the bracket in holding the arm parallel with said side of the door when the foot is in the inverted position.
